Best Answer

Gear ratios will let the engine run at the speed and load at which it is most efficient, which is good for low fuel consumption and an exhaust that is as clean as possible.

What is fuel air ratio?

Air to fuel ratio is the ratio between the weight of air to the weight of fuel, for example: 14.7 pounds of air to 1 pound of fuel would be a air:fuel ratio of 14.7:1 This particular example is called the stoichiometric ratio for gasoline...it's ideal ratio in order to efficiently use all the fuel. This ratio varies for different fuels....for example, ethanol fuels have a stoichiometric air:fuel ratio of 13.85:1. In actuality, a gasoline car gets it's best fuel mileage when the fuel is reduced slightly and produces it's best power when the ratio is a little heavier on the fuel side.

Lube oil consumption of diesel engine?

Lube oil consumption depends on engine design and motor operating conditions. Dieselnet is a good source. Typical oil consumption values for pre-1980s engines were 0.46 g/kWh (0.34 g/bhp-hr; 0.25% of fuel consumption), pre-1990 engines ranged between 0.33-0.48 g/kWh (~0.15 - 0.20% of fuel consumption). A test on a number of 2002 heavy-duty and medium-duty engines in the US yielded an average of 0.22 g/kWh (0.1% of fuel consumption). Year 2007 heavy- and medium-duty engines consume on average 0.08 g/kWh (around 0.03% of fuel consumption)


Which calculator helps to calculate fuel consumption?

A pen and paper. Miles driven divided by gallons of fuel used gives you mpg.

Is fuel consumption high in Low gears or in high top gears?

generally speaking, fuel consumption is higher in low gears because the rpm of the engine is higher. Performance is measured in kilometers/gallon. You have to consider that cars are designed for optimum performance when you drive at around 80 km/hr. For each car there is an optimum ratio distance/fuel consumption.
